HUBERT VAN W. MYER, OF NEWARK, NEW JERSEY.

LIFT-PUMP VALVE.

SPECIFICATION forming part of Letters Patent No. 228,668, dated June 8, 1880.

Application filed April 14, 1880.

To all whom it may concern:

Be it known that I, HUBERT VAN W. MYER, of the city of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Lift-Pump Valves, of which the following is a description.

My invention relates to an improvement in pump-valves and it consists in a novel means of constructing and attaching the valve to the hand lift-pumps usuallymade with thin sheetmetal barrel. The ring usually soldered into such barrels is deprived of its feet, and an auxiliary foot-piece carrying a disk-valve made entirely of metal is seated upon a ring of packing supported upon the foot-piece, the latter being held to the. pump-ring by a nut and a stud secured to a bridge above the valve.

Figure l of the drawings is a sectional elevation through the center of my improved valve and a portion of the pump-barrel. Fig. 2 is a plan of the metallic disk-valve A; Fig. 3, apacking-washer,a, employed at the center of the valve upon the foot-piece B. Fig. at is a plan of the packing-ringb, employed at the margin of the foot piece to make the joint between the valve and the foot-piece and between the latter and the pump-ring C. Fig. 5 is a side elevation of the pump-ring, showing a recess, 0, in its lower side, into which the foot-piece fits to prevent displacement, and two posts, D, provided upon opposite sides of the top of the ring to carry a bridge, E. Fig. 6 is an end view of the bridge which is shown in Fig. 1, with the stud (1 depending from its middle to guide the disk-valve when lifting, and to hold the ring to the foot-piece by the nut 0, applied to its lower end. Fig. 7 is a top view of the ring, having the bridge placed in position, the top of the posts D being preferably formed with dovetailed notches f and the ends of the bridge fitted into the same. Fig. 8 is a bottom view of the foot-piece B, showing the feet F, which may be made of any desired number, and the cross-bar G, adapted to receive the stud (I through a hole, g, formed in its middle, whereby it is clamped to the pump-ring O. The washer-a rests upon this cross-bar around the hole 9 and packs the valve A at this point. The foot-piece is of ringshape, with its upper surface wide enough to lit the packing-rin g Z), and having the ring-seat. elevated alittle to fit the recess 0 in the pump-rin By the construction shown the valve moves freely up and down upon the stud d, between the posts D, and makes a tight joint upon (No model.)

the foot-piece B, although made entirely of metal.

The only part of the valve requiring renewal is the ring I) and washer to, which can bereadily cut from rubber or leather with an ordinary knife. The foot-piece can be readily detached from the pump for. that purpose by unscrewing the nut c from its stud, and

as readily replaced when the packing is in-' serted.

I am aware that detachable valves are not new, and that a loose ring has been detachably connected to the bottom of a pump, as in Patent No. 23,937, granted to J. Munson in 1859; but such a valve is not adapted to the situations for which mine is intended, as it is not designed to be used with the thin sheet-metal pumps used for pumping oil and liquor from barrels, 850., and is not, therefore, constructed to be held in the barrel of apum'p like mine. Neither is it capable of such convenient and economical repairs as mine, wherein the packings are not secured by rivets or other permanent fastenings, but can be readily detached and new ones out out with an ordinary pocket-knife, and applied without tools or mechanical skill. Neither has his any packing-ring which serves. the double function of seating the valve and making the joint between the foot-piece and the pump. I therefore consider the essential features of my invention to be the metallic valve guided by a central stud, which holds the foot-piece to the pump, and the packing-ring, which serves to make a seat-joint for the valve, and the joint between the foot-piece and pump-ring, as herein described. I therefore claim'my invention as follows:

In a pump-valve having a removable footpiece, B, the combination of the metallic disk- 5 valve A with the bridge E, above the valve, carrying a central stud, d, to guide the valve and clamp the foot-piece to the pump, and the packing-ring 1), serving to seat the valve upon the foot-piece and to pack the joint between the foot-piece and the pump-ring, in the manner shown and described.

In testimony that I claim the foregoing I have hereto set my hand this 10th day of April, 1880, in the presence of two witnesses.
